ROLLER-SHADE HOLER.

SPECIFICATION forming part of Letters Patent No. 411,775, dated October 1, 1889.

Application filed April 12, 1889.

.To @ZZ whom, it may concern:

Be it known that l, ELIAS BEACH, a citizen of the United States, residing in Chicago, in the count-y of Oook and State of Illinois, have invented a new and useful Improvement in Roller-Shade Holders, of which the following is a specification,

My invention relates to improvements in roller-shade holders or devices by which the paper or other shade is secured to the revolving rollerupon which it is carried and around which it is Wound.

It is the object of my invention or improvement to provide a construction of sheet-m etal roller-shade holders which will increase their eiiicieney and durability, whereby the cost of the holders may be diminished, and which at the same time will not interfere in any way with the rolling or winding of the shade smoothly on the roller.

I have discovered, and herein my invention consists, that by providing the back or central portion of the curved sheet-metal holder with one or more (preferably three) raised ribs or beads stamped in the sheet metal substantially as shown in the accompanying drawings, the holder may be madeof much lighter and cheaper stock withoutin anyway detracting from the efficiency of the holder.

In the accompanying drawings, which form a part of this specification, and in which similar letters of reference indicate like parts, Figure l is a front elevation showing a shade and roller with my improved holder applied. Fig. 2 is a side elevation of the holder; Fig. 3, a back View; Fig. 4, an end view, and Fig. 5 a section on line 5 5 of Fig.

In the drawings, A represents a windowcasing; B, the shade; C, the roller, and l) the curved Sheet-metal holder by which the upper end of the shade is secured to the roller.

The holder D is made from a blank of sheet metal curved into somewhat more than semicircular form, as clearly indicated in Figs. 4 and 5, so as to properly clamp over the roller Serial No. 306,948. (No modell) O, and it is provided with transverse raised ribs or beads CZ, preferably three in number, located on the back or central port-ion of the holder and extending, preferably, about halfway from the middle line, on each side thereof,

of the holder to its two Afree edges d, as is clearly indicated in Figs. 2, 3, and 5. These beads should be about one-quarter of an inch in width and taper at their ends into the curved surface of the holder, as is shown in Figs. et and 5. rlhis tapering of the beads at their ends aids in giving the proper spring action to the free edges d d of the holder. The beads or ribs rl are formed by stamping the blank, and are raised, preferably, to the thickness of the tin or sheet metal, as is indicated in Figs. 2, 4, and 5. In practice the holders furnished with these ribs are made about three inches in length.

rlhe ribs or beads tl sti ffen and give greater clam ping-power to the central or body portion of the holder witho ut destroying the resilience of the longitudinal edges.

I am aware of the construction of holders shown in patents to Mosher, No. 248,494, Oetober 1S, 1881, and to RosclnNo. 320,200, June 1G, 1885, and disclaim the same.

I claiml. The sheetmetal rollershade holder made semieireular, so as to conform to the surface of the roller, and provided at its central portion with stiffening-indentations, substantially as specified.

2. The sheet-metal clamp for roller-shades, made scmieircular, so as to conform to the surface of the roller, and provided with central transverse in den tat-ions, whereby the lon gitudinal center of the clamp is rendered stitfer than the edges thereof, substantially as specified.

ELIAS BEACH.
